High-capacity DDR5 kit for Thinkmate workstations

This 1.5 TB kit contains twelve 128 GB DDR5 modules built for the Thinkmate GPX-XS8-24S4-4GPU workstation. Each module runs at 4800 MT/s with a CAS latency of 40 and operates at 1.1 V. The registered ECC design uses 4Rx4 organisation to maintain data integrity across all channels.

Suited for memory-intensive server workloads

The kit targets IT teams who need maximum registered ECC capacity in a validated Thinkmate configuration. It is not for buyers who require unbuffered memory, non-ECC modules or lower-density sticks for consumer platforms. Systems that cannot accept 288-pin DDR5 RDIMMs or that limit total memory below 1.5 TB should look elsewhere.

Steady throughput under sustained load

Registered buffering and on-die ECC keep error rates low during continuous compute tasks such as virtualisation, rendering or large-dataset analysis. The 1.1 V operating voltage helps control thermals when all twelve slots are populated for extended periods. Modules are stress-tested at rated speed to verify stability before shipment.

Questions about this item

Do I need a ThinkMate GPX-XS8-24S4-4GPU workstation with twelve free 288-pin DDR5 RDIMM slots to use this 1.5 TB kit?

Yes, the kit contains twelve 128 GB DDR5 4800 CL40 ECC registered modules that only fit a system with twelve matching DDR5 RDIMM slots, such as the ThinkMate GPX-XS8-24S4-4GPU.

Can I mix these 4Rx4 DDR5 4800 CL40 modules with any other DDR5 RDIMMs already installed in my ThinkMate GPX-XS8-24S4-4GPU?

Mixing is only reliable when the existing modules share the same 4800 MT/s speed, CL40 latency, 1.10 V voltage, 4Rx4 rank layout and ECC registered design; otherwise the system will down-clock or fail to boot.

How can I confirm the full 1.5 TB is recognised and running at DDR5 4800 CL40 after installation?

Enter the BIOS or run a memory utility such as dmidecode and verify that all twelve slots show 128 GB each, speed reads 4800 MT/s (PC5-38400) and CAS latency reads CL40.
